Cast Iron Roller Chain Sprockets \u2014 Low-Speed, High-Torque Drives<\/h2>\n

Cast iron sprockets are specified for low-speed, high-torque applications where the inherent vibration damping properties of cast iron provide smoother, quieter operation than steel. GG25 grey cast iron construction also offers moderate corrosion resistance without surface treatment, making cast iron sprockets suitable for outdoor, agricultural, and water treatment environments. Available in ISO 08B-32B and ANSI #40-#160 with tooth counts from 9 to 120.<\/p>\n

Why Cast Iron?<\/h2>\n
\n
\n

Vibration Damping<\/h4>\n

Cast iron absorbs vibration inherently. Quieter, smoother operation than steel at low speeds.<\/p>\n<\/div>\n

\n

Self-Lubricating Properties<\/h4>\n

Graphite flakes in grey cast iron provide natural lubricity at the tooth-roller interface.<\/p>\n<\/div>\n

\n

Moderate Corrosion Resistance<\/h4>\n

Better atmospheric corrosion resistance than untreated carbon steel. Suitable for outdoor and damp environments.<\/p>\n<\/div>\n

\n

Cost Effective for Large Sizes<\/h4>\n

Cast iron sprockets are more economical than machined steel for large-diameter, low-speed applications.<\/p>\n<\/div>\n<\/div>\n

Not suitable for:<\/strong> High-speed drives (>300 RPM), shock loading, or applications where tooth breakage could cause safety hazards. Use steel sprockets for these conditions.<\/p>\n

Applications<\/h2>\n
\n
\"CI<\/p>\n

Agriculture:<\/strong> Low-speed barn conveyors, manure handling, irrigation equipment, hay baler drives.<\/p>\n<\/div>\n

\"CI<\/p>\n

Water & Wastewater:<\/strong> Bar screen rakes, sludge scraper drives, slow-speed clarifier mechanisms.<\/p>\n<\/div>\n<\/div>\n

Reviews<\/h2>\n
\n
\n

“Cast iron 12B on our wastewater bar screen. Quieter than the steel sprocket it replaced. No corrosion after 2 years outdoors.”<\/em> ★★★★★ \u2014 Asset Eng., Melbourne Water, Australia<\/p>\n<\/div>\n

\n

“CI sprockets for our barn conveyor. Low speed, no vibration, handles the damp environment well.”<\/em> ★★★★★ \u2014 Farm Manager, Gippsland, Australia<\/p>\n<\/div>\n

\n

“Cost-effective replacement for our large-diameter slow-speed drive. Cast iron was the right choice.”<\/em> ★★★★☆ \u2014 Maint Mgr, Surabaya, Indonesia<\/p>\n<\/div>\n

\n

“Legacy equipment replacement. Cast iron CI sprocket matched the original dimensions exactly.”<\/em> ★★★★★ \u2014 Plant Eng., Christchurch, New Zealand<\/p>\n<\/div>\n

\n

“Good quality GG25 cast iron. We use these for outdoor agricultural conveyors.”<\/em> ★★★★★ \u2014 Buyer, Pretoria, South Africa<\/p>\n<\/div>\n<\/div>\n

FAQ<\/h2>\n
\nCast iron vs steel?<\/summary>\n
Cast iron: quieter, self-lubricating, corrosion-resistant, lower cost for large sizes. Steel: higher strength, shock resistance, suitable for high speed. Choose based on your speed, load, and environment.<\/div>\n<\/details>\n
\nMax speed for CI sprockets?<\/summary>\n
Recommended maximum ~300 RPM. Above this, steel sprockets are preferred due to impact fatigue concerns.<\/div>\n<\/details>\n
\nDuctile iron available?<\/summary>\n
Yes on request. GGG40\/GGG50 ductile iron for higher strength requirements while retaining vibration damping.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
Depends on size. Generally larger bores available than equivalent steel due to larger hub diameters.<\/div>\n<\/details>\n
\nMOQ?<\/summary>\n
One piece for stocked sizes. Custom casting MOQ 50+ for non-standard sizes.<\/div>\n<\/details>\n
